• Magnetostriction and magnetization measurements on nonsuperconducting TbNi2B2C crystals and on superconducting Tb0.3Y0.7Ni2B2C single crystals were carried out in magnetic fields up to 8 T. Besides the antiferromagnetic transition at 15.5 K and the ferromagnetic transition at 9 K, isothermal scans on TbNi2B2C crystals show further three metamagnetic transitions, which vanish for temperatures greater than 10 K. Isofield measurements on the Tb0.3Y0.7Ni2B2C single crystals show a antiferromagnetic transition at 3.6 K. Furthermore our investigations indicate a ferromagnetic transition at 1.26 K. Investigations perpendicular and parallel to the 001-axis of the Tb0.3Y0.7Ni2B2C single crystals show a pronounced anisotropic behavior.
